Abstract:
The emission of e(+)e(-) pairs from C + C collisions at an incident energy of 1 GeV per nucleon has been investigated. The measured production probabilities, spanning from the pi(0)-Dalitz to the rho/omega invariant-mass region, display a strong excess above the cocktail of standard hadronic sources. The bombarding-energy dependence of this excess is found to scale like pion production, rather than like eta production. The data are in good agreement with results obtained in the former DLS experiment. (C) 2008 Elsevier B.V. All rights reserved.
